Description

Hose clip

Technical field

The present invention relates to according to the preamble of claim 1, be preferred for clamping the hose clip of conduit elongated portion.

Background technology

Disclose this hose clip, for example, described a kind of hose clip in European patent application publication No. EP 0 995 461A1, it comprises the plastic body of the integral body of elongated shape itself, this plastic body have two in the end interconnected jig arm.In the inboard of these two jig arm, projection of two each self-formings of jig arm, these two projectioies are opposed mutually under the hose clip closure state, and the size of these two projectioies can make its squeezing tube.Under the state of hose clip closure, two jig arm hook mutually connect together.On the front-end and back-end of hose clip, hose clip has the hole respectively, by described hole, can admit flexible pipe such as conduit elongated portion.

This class hose clip for example is used on the conduit elongated portion in the peritoneal dialysis field.At this moment, hose clip is positioned at patient's abdominal part adapter place, is used for open and close to be positioned at conduit elongated portion on the abdominal part adapter.Hose clip contacts patient skin for a long time, so concerning known anchor clamps be applicable in principle other anchor clamps this purposes, that can buy, owing to have burr and seamed edge, from then on usually skin is caused stimulation on market.Size and dimension also makes the patient feel bad.

Summary of the invention

Therefore, the objective of the invention is so to improve known hose clip, promptly the patient thinks no longer that when carrying hose clip is undesirable.

According to the present invention, utilize the hose clip have according to the characteristics combination of claim 1 to realize this purpose.Therefore, in fact hose clip is the cylindrical shape of two ends through excision, and this cylinder is being conical taper on the direction at two ends, and two ends are matched with the round-shaped of the flexible pipe that is inserted into.The conception of this novel shape of hose clip is that its basic configuration comes from cylinder, and its two ends are designed to tapered taper shape.In order to obtain the big as far as possible comfortableness of carrying, the shape of hose clip will be matched with the shape of flexible pipe.

Favourable scheme of the present invention comes from the dependent claims that is subordinated to independent claims.Therefore, all marginal area of hose clip is all rounded, eliminates sharp edge and wedge angle thus.

According to a preferred embodiment of the present invention, hose clip length is no more than 10 times of hose diameter.And the radius of rounded plastic body is favourable between R20 to R30.

In addition, plastic body becomes 5 degree according to relative longitudinal axis to extend to its both ends is favourable to the modes at 40 degree angles.Like this, between flexible pipe and hose clip continuous transition can appear.According to another preferred version, the outermost point of the hose clip under the closure state is the twice of hose diameter to the ultimate range at the center of the flexible pipe that will insert.Limit longilineal hose clip thus, it can not make the patient feel unhappy again.

On roughly cylindrical outer surfaces two jig arm, former, cut hand-held face, to obtain easy operating characteristics.

Advantageously, hook connect mechanism on the one hand by on the hose clip end towards the free-ended projection of jig arm and form by the butt limit that on the jig arm free end, forms on the other hand., form operating surface here above the projection on the hose clip free end, the elastic tip of hose clip can be displaced to unlocked position from locked position by this operating surface.Thus one, can guarantee that hose clip can be closed and open repeatedly.

Description of drawings

With reference to embodiment shown in the drawings, can obtain other details of the present invention and advantage, wherein:

The specific embodiment

A kind of hose clip according to an embodiment of theinvention 10 has been shown among Fig. 1.Hose clip 10 comprises the plastic body of the integral body that is the strip extension, and this plastic body has twojig arm 12 and 14.Two jig arm interconnect in theend 16 of hose clip, under unloaded state, andjig arm 14relative jig arm 12 deflection angle a.Aprojection 18 and 20 are respectively arranged onjig arm 12 and jig arm 14.Can close by the flexible tube section that these two projectioies will be gone here and there on this hose clip.The elastic force thatjig arm 14 can overcomeend 16 rotates towardsjig arm 12 directions, and under closure state,jig arm 14 connects withend 22 mutual hooks.Hook connect mechanism on the one hand by on the end ofhose clip 10 towards jig arm free-ended protruding 24 and form by thebutt limit 26 that on the jig arm free end, forms on the other hand.On the front end that corresponding mutually inclined-plane 28 and inclined-plane 30 are arranged inbutt limit 26 and on the respective end ofprojection 24, described inclined-plane causesend 22 outwards to be offset when pressing downjig arm 14, thereby makebutt limit 26 be positioned at the below ofprojection 24, the hose clip hook connects and is closed thus.

In addition, formoperating surface 32 on the free end of hose clip, theelastic tip 22 of this hose clip can be displaced to unlocked position from locked position by this operating surface.

Especially can be as seen from Figure 4,circular port 34 is arranged in the zone of leadingsection 22, and still, circular port also is arranged on the zone interior (not being shown specifically at this) ofrearward end 16, and flexible pipe or conduit are inserted in the hose clip by described circular hole.

Hose clip 10 has and is similar to the cylindrical shape that two ends have excision face.Cylinder towards theend 16 andend 22 be conical taper, eachend 16 and 22 has respectively and is matched with the round-shaped of circular hose to be inserted.Here, all marginal zones of hose clip are all rounded, as according to shown in the A-A sectional view of thejig arm 12 of Fig. 3.

Especially can from Fig. 5 and Fig. 6, find out, on the periphery ofjig arm 12 andjig arm 14, form planar section respectively, can obtain easy operating characteristics like this as hand-heldface 36 and 38.
